(Cl. zosa Thisinvention relates to windows and is more par} ticula'rly concerned withwindow construction wherein the sash is mounted for rotation. I

In its more specific phases the invention contemplates a sash rotatablymounted in a frame, whereby the sash may be rotated through 360 degreesof are for washing the window pane or panes, or for providingventilation.

The invention is also concerned with locking and sealing means forlocking the sash in a closed position and for sealing it against theweather. Preferably the sash will be pivoted in the window frame alongarh'edial horizontal line, although rotation about a medial verticalline also is contemplated.

A further object of the invention is a locking and sealing mechanism forthe sash cooperating with all four edges thereof, but releasable by asingle manual operating member when the sash is to be rotated forcleaning or providing ventilation.

Yet another object of the invention is a releasable locking and sealingmechanism for the sash which can'- not be released from the exteriorside 'of the sash, but which is readily releasable by a single manualoperating member disposed on the interior side of the sash.

The invention is particularly applicable to large horizontally disposedor picture windews which heretofore could not be opened for ventilation.v I

With these and other objects in view whichniay ap pear while thedescription proceeds the i'nve'ntion consists in the novel arrangementof eoopera'tihg pans; shown in the accompanying drawings forming part ofthis application and in which:

Figure l is a perspective view of one embodiment of the inventionshowing a single sash rotatably mounted in a frame;

Figure 2 is a typical transverse section of this embodiment showing thesash in a closed position;

Figure 3 is a section taken along the axis of rotation of the sash, buton a larger scale;

Figure 4 is a partly diagrammatic part view similar to Fig. 2, showingthe sash in an almost closed position and upper locking means for thesash, and

Figure 5 is a schematic view of the releasable locking and sealingmechanism for the sash.

The invention here is illustrated with the sash adapted for openinginwardly at its bottom, although the invention also contemplates a sashopening inwardly at the top, this being effected by simply reversing therelative position of the locking mechanism in the frame.

In the drawings, wherein like characters of reference denote the sameparts throughout, the numeral represents a window frame which isfabricated in more or less usual manner of wood or metal stock. A sash11 is so mounted in the frame 10 that it is rotatable about a medialhorizontal axis as shown in Fig. 1, this mounting being effected bysuitable pivot pins 12 disposed on opposite vertical edges of the sash,which pins cooperatively engage suitable bores or bearings 13 formed inor secured in opposite vertical sides of the said frame.

' 2,728,960 Patented Jan. 3, 1956 The glass pane 14 is carried dir'ectlyby the sash, although the glazing may be subdivided into smaller panesor lights by the usual niuntins, if desired.

The body of the sash 11 is formed of four rails constituting itsrespective sides, top, and bottom, the rails being mitered or suitablyjoined at the corners, and rabbe'ted to receive the pane 14. Preferablythe rails are fabricated from wood stock having one more or less roundededge, but it is contemplated that extruded metal stock will be requiredin sashes of large size.

The frame 10 may be of any suitable cross section and material, but, inthe form shown, is built up of four wood members constituting itsrespective sides, sill, and top, these members being joined in usualfashion at the corners.

Each side of the frame 10 is formed with a longi;

tudinal groove or rabbet 15 for the reception of sash sealing strips 16which also act as locking means which are held in position by meansshortly to be described. The inner surface of each sealing strip isnormally in contact with the outer faces of the Side rails of the sashwhen the sash is in a closed position. In like manner the sill and topof the frame 10 are formed respectively with a longitudinal groove orrabbet 17and 18 for the reception of sash locking strips 19 and 20,which strips are held in position by means to be described. The outersurface of the lockin strips 19 and 20 are normally in contactwith theinner faces of the top and bottom rails of the sash 11 when the sash isin a closed position.

The sealing strips 16 are disposed in the grooves 15 in thesides of theframe 10 for limited sliding movement in and out of the grooves, andnormally are urged to an outwardly position by tensed expansible elasticmembers which may be coil springs as at 21, and which are disposed inthe grooves 15 and beneath the sealing strips 16. The said sealingstrips may be made of metal, but preferably, as shown, are wood barsformed with outer round- 'ed corners.

The locking strip 19 is formed similarly to the sealin g strips 16 andis similarly disposed in the groove 17 which extends across the sill ofthe frame 10, being urged outwardly by other tensed expansible elasticmembers such as the coil springs 22.

The locking strip 20 is disposed in the groove 18 formed in the top ofthe frame, for limited sliding movement in and out of the groove, beingurged outwardly by tensed expansible elastic members, e. g.coil springs23, as hereinb'efore set forth for the sealing strips 16.

The locking strip 20 may be made of metal, but, as shown is a wood barformed in more or less wedge shape, the butt of the wedge being normallyin contact with the top rail of the sash 11. The locking strip 20preferably is provided with an upper flange (not shown) and is securedby a slotted plate (also not shown) countersunk into the top of theframe 10, the said flange taking up on the upper side of the said platewhen the locking strip is in the most outwardly position.

The locking strip 19 is operatively connected to each of the sealingstrips 16, preferably by lengths of corrosionresisting steel wire orcable 24, but other materials may be provided. The wires 24 pass throughbores formed in the frame 10, pass over a plurality of sheaves 25 whichare carried in a plurality of suitable brackets 26 attached on oppositesides of the frame, pass again through other bores in the frame 10, andare connected more or less medially of the sealing strips 16 in a mannersuch that the locking strip 19 and sealing strip 16 are normally in amost outwardly disposition in the grooves 17 and 15 respectively.

The fitting of the sealing strips 16 into the grooves 15 rotation andefiecting a weather seal between the sashand the frame 10, while thefitting of the locking strips 19 and 20 respectively into grooves 17 and18 permit a direction of rotation of the sash such that it can be openedonly from one side, i. e.the inner side of the sash.

Sealing of the top and bottom rails of the sash 11 against the weatheris effected by fitting rain deflectors to opposite sides of the saidrails as at 27. The deflectors 27 preferably are fabricated of ayieldable material, e. g. rubber, to closely engage adjacent portions ofthe frame while still permitting free movement of the said de flectorsover the said sealing and said locking strips.

The construction of the Window is such that the need for the usuallocking means is obviated but other hardware, e. g.hand pulls 28, areattached to the top and bottom rails of the sash 11 for opening andclosing the sash. A cover 29 is provided for the sheaves 25 beingattached to the sides of the frame 10 by suitable fasteners.

When it is desired to open the sash for cleaning or to provideventilation, the locking strip 19 is pushed downwardly into the groove17 in the sill of the frame, thereby tensing the steel wires 24 andcausing the sealing strips 16 to be drawn into the grooves 15 in thesides of the frame 10. The sash 11 may then be pulled inwardly at thebottom (by grasping the hand-pull 28) to any desired position, beingfrictionally held in the selected position by the outward pressureexerted by the sealing strips 16 on the side rails of the sash, when thelocking strip 19 is released. This pressure is imparted to the sealingstrips, of course, by untensing of the coil springs 21, 22 and 23.Closing of the sash is effected by further rotating the frame through atotal are of 180 degrees whereupon the locking strip is wedged home intothe groove 18 by the passing top rail of the sash until the sash iscaused to assume a vertical position in the frame. The inwardly actingpressure of the sash 11 on the sealing strips 16 and locking strip 20then being relieved, the said strips return to the normal dispositionthus effectively locking the sash 11 in a closed position. It is evidentthat rotation of the sash will be unidirectional at all times and thatthe sash may be passed through a full 360 degrees of arc, in 180 degreesteps. A fully rotary window, unlockable from the outside, thus isprovided.

It is believed that the construction and advantages of the structureshown may be apparent from the foregoing paragraphs taken in conjunctionwith the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it isunderstood that minor changes in the construction, combination andarrangement of cooperating parts may be resorted to within the scope ofwhat is claimed without departing from the spirit of the invention.
